typora 标题自动加编号

网上看了挺多其他复制粘贴的方法，但是缺点都是第一级 h1 ,都算进去了

按照规范的 markdown 规范，一个 md 文件中只能出现一个 h1,就是标题

所以最大的编号应该就是 h2,所以我拿来改了一下

新建样式

在 Typora\themes 目录下,新建一个base.user.css文件

导入我修改好的 css

已经集成了 标题自动编号, TOC 目录自动编号, 左侧导航栏自动编号

编号默认从 h2 开始计算

/** initialize css counter */
#write {
    counter-reset: h1
}
 
h1 {
    counter-reset: h2
}
 
h2 {
    counter-reset: h3
}
 
h3 {
    counter-reset: h4
}
 
h4 {
    counter-reset: h5
}
 
h5 {
    counter-reset: h6
}
 
/** put counter result into headings */ 
#write h2:before {
    counter-increment: h2;
    content: counter(h2) ". "
}
 
#write h3:before,

    counter-increment: h3;

然后开始使用

需要注意的是，只有导出 html 的时候才能看得见这个样式，如果是直接复制是无法复制走这个序号的，如果想要复制的时候也有需要请自己写 python 脚本，或者有时间我可能会写一个
